ROLLER, BUMPER, 8:0.

To all whom it may concern:

Be it known that I, HARRY F ILLMORE PENnLE'roN, residing at Brooklyn, inthe county of Kings and State of New York, have invented certain new anduseful Improvements in Rollers, Bumpers, and Similar Articles, of whichthe following is a specification.

This invention relates to rollers, bumpers, and similar articles, theproduction of articles of the class described, comprising a core ofrelatively porous and preferably flexible material, such as rope, uponand partly within the interstitial spaces of which is immovably held asuitable covering, such as vulcanized rubber.

Another object of the invention is to duce, as a new article ofmanufacture, a bumper or the like comprising a core provided withinterstitial spaces, and a covering of vulcanized material compressedradially thereupon and engaging said spaces.

The characteristics of this invention, together with a process by whichit may well be manufactured, will be hereinafter explained, referencebeing had to the accompanying drawing, in which Figures 1 and 2 show theparts of an ordinary mold such as may be used in producing my invention,while Fig. 3 shows the completed article.

Referring to the numerals on the drawing, 1 indicates the cavities ofcorresponding mold sections, adapted to receive the rope core 4, whichis here shown as made up of twisted strands.

2 and 3 indicate egress channels for the rope, and it will be understoodthat while the rope or core is tightly inclosed within the egresschannels, the cavity 1 is larger in diameter, than the core. This is inorder that the rubber to be vulcanized upon the core may be placedaround it within the promold. The material within the mold may then besubjected to vulcanizing heat while the mold sections are held tightlytogether, the necessary vent of the mold being through the core andchannels 2 and 3. It is evident that the expansion of the rubber in thevulcanizing process will force it into the depressions of the rope orcore, and cause it to Specification of Letters Patent.

grip the latter firmly. The materials employed are the usual ones forthis purpose, and the heat is applied in the usual manner. The resultantproduct shows that the rubber I is forced into the most minutedepressions upon the surface of the core, and even into i theinterstices below the surface, so that I their union is practicallyindissoluble. rticles made in accordance with this invention are capableof wide employment, in appropriately modified forms, as rollers, orbumpers, or wherever their qualities of fleXibility, elasticity, andtensile strength may be required. I The present invention includessubject- I matter divided out from my application, Serial N 0. 402,233,filed November 15th, 1907, for methods of vulcanizing rubber andarticles made thereby.

Having thus described my invention what I claim as new ters Patent is:

1. As an article of manufacture, a fibrous rope core provided with acovering of vulcanized material compressed radially thereupon.

2. As an article of manufacture, a fibrous rope core made up of twistedstrands, and provided with a covering of vulcanized material compressedradially thereupon.

3. As an article of manufacture, a fibrous rope core provided with acovering of vulcanized material compressed radially thereupon and partlyinto the interstices thereof.

s an article of manufacture, an elongated fibrous core provided withinterstitial spaces, and a covering of vulcanized material compressedradially thereupon and entering said spaces.

5. As an article of manufacture, a flexible elongated fibrous coreprovided with interstitial spaces, and a covering of vulcanized materialcompressed radially thereupon and entering said spaces.

In witness whereof I aflix my signature in the presence of twowitnesses.
